Robot company Jibo has raised an additional $12 million in venture funding after announcing it had raised $25.3 million earlier this year, according an a filing with the SEC.

Jibo’s total funding for the round, according to the amended filing, is now $37 million. The new money came from an additional four unidentified investors.

A robot designed to help families, Jibo acts as a personal assistant, sending messages, coordinating appointments and even telling bedtime stories. Jibo was founded by MIT professor and robotics pioneer Cynthia Breazeal.

Jibo originally took to crowd-funding website Indigogo, blowing its $100,000 goal out of the water. The company ended up raising $2.3 million.
